It seems that the SelectObjects function is not working:

# get list of selected props
selectedProps = []
prop = RLPy.RScene.FindObject( RLPy.EObjectType_Prop, 'Ball_000' )
if prop:
selectedProps.append(prop)
prop = RLPy.RScene.FindObject( RLPy.EObjectType_Prop, 'Ball_001' )
if prop:
selectedProps.append(prop)

# select props in ic
res = RLPy.RScene.SelectObjects(selectedProps)

When it tries to execute the SelectedObjects command ic freezes and crashes.
